Google Photos Library API Java Client Library

This repository contains the Java client library for the Google Photos Library API.

Build Status

Requirements and preparation

  • Java 1.8+
  • Gradle build system or Maven 3.0+ recommended.
  • OAuth 2.0 credentials configured for your project as described below. (Note that to run the samples, use the "other" client type.)

Download the client library

Firstly, download the library or include it in your build configuration. Then, set up OAuth 2.0 credentials to access the API.

Next, you can follow the samples to see the client library in action.

Option 1: Gradle dependency

To use this library with Gradle, add the following dependency to your build.gradle file:

repositories {
    mavenCentral()
}
dependencies {
    compile 'com.google.photos.library:google-photos-library-client:1.2.0'
}

Option 2: Maven dependency

To use this library with Maven, add the following to your Maven pom.xml file:

<dependency>
  <groupId>com.google.photos.library</groupId>
  <artifactId>google-photos-library-client</artifactId>
  <version>1.2.0</version>
</dependency>

Option 3: Download a release

The releases page contains different artifacts for each library release, including jar files.

Option 4: Clone the repository

Use this method if you want to alter or contribute to this library (e.g., submitting pull requests) or wish to try our samples. When you clone the repository, all files in this repository will be downloaded.

  1. Run git clone https://github.com/google/java-photoslibrary.git at the command prompt.
  2. You'll get a java-photoslibrary directory. Navigate to it by running cd java-photoslibrary.
  3. Open the build.gradle file in your IDE or run ./gradlew assemble at the command prompt to build the project. See ./gradlew tasks to see available tasks

Set up your OAuth2 credentials for Java

The Google Photos Library API uses OAuth2 as the authentication mechanism. Note that the Library API does not support service accounts.

To complete the “Enable the API” and “Configure OAuth2.0” steps in the below procedure, refer to the get started guide in the developer documentation

Follow the below steps:

  1. Set up a Google developers project
  2. Enable the Google Photos Library API in your developer project
  3. Configure OAuth 2.0 credentials, including a callback URI
  4. Either download your OAuth credentials as a JSON file or note your client ID and secret.

To try out the samples in this repository, select "other" as the application type.

This client library works with the Google Auth Library for Java. Specify your client OAuth configuration in the CredentialsProvider when creating the PhotoLibrarySettings for a PhotosLibraryClient object. See the file PhotosLibraryClientFactory.java for an example on how to create a new PhotosLibraryClient object with credentials from the Google Auth Library.

Sample usage

Here's a short example that shows how to create a new album:

// [START sample_usage]
// Set up the Photos Library Client that interacts with the API
PhotosLibrarySettings settings =
     PhotosLibrarySettings.newBuilder()
    .setCredentialsProvider(
        FixedCredentialsProvider.create(/* Add credentials here. */)) 
    .build();

try (PhotosLibraryClient photosLibraryClient =
    PhotosLibraryClient.initialize(settings)) {

    // Create a new Album  with at title
    Album createdAlbum = photosLibraryClient.createAlbum("My Album");

    // Get some properties from the album, such as its ID and product URL
    String id = album.getId();
    String url = album.getProductUrl();

} catch (ApiException e) {
    // Error during album creation
}
// [END sample_usage]

Samples

A few examples are included in the sample directory. They show how to access media items, filter media, share albums and upload files.

The API developer documentation also includes code snippets for this client library in Java.

Reference documentation

Javadoc for this library can be found in the gh-pages branch of this repository. You can browse it at https://google.github.io/java-photoslibrary/index.html
